dear @TeamYouTube, just because I decide to look up a few phone reviews, one after another, does not mean I want my recommended filled with phone channels for weeks. Also, please stop using Autoplay as a metric to decide what I want. Most the time I am asleep or busy!
I use auto play when watching music videos while playing games and that works quite well but If I watch a one off longer video then leave it on, it could auto onto many of the same topic videos, pushing it up my recommendations.
